This code seems to work, it is able to create an `ipc::IpcWriteOptions` with the compression field set, and pass it along with the dataset writer. The files written with e.g. lz4 are much smaller, so it seems to actually compress the data. However, there is something weird about the `compression` field (this is a `std::shared_ptr<util::Codec>` that is created in Python). I can set the field, but I cannot read it back (it will just return `None`). The other fields can be read back. Note that the code that is supposed to return the name of a Code already existed. -- This is an automated message from the Apache Git Service.
